Definitions

the invention relates to a fifth wheel for coupling a tractor unit with a semi-trailer with connection arrangements for connecting electrical and pneumatic or hydraulic lines according to the preamble of claim 1.
the semi-trailer is coupled to the towing vehicle by means of a fifth wheel.
the fifth wheel essentially comprises a fifth wheel with a closing device on the towing vehicle and a so-called kingpin on the semitrailer.
further, e.g. electrical, hydraulic and pneumatic connections between the towing vehicle and the trailer are made.
these compounds are individually connected via flexible cables. This is complex and time-consuming for the driver when coupling and uncoupling the semitrailer.
the DE 842 895 relates to a coupling device for trailers of semi-trailers with a vertically slidable in the vertical direction, sitting on the tractor coupling pin and a cooperating with this pin, provided on the trailer coupling sleeve.
the CA 2 434 623 refers to a fifth wheel for coupling a tractor vehicle with a semi-trailer, wherein the semi-trailer has a kingpin and the towing vehicle has a cooperating with the kingpin coupling plate.
the DE 296 16 253U relates to a fifth wheel for the coupling of a tractor with a semitrailer, with a clutch plate, a kingpin engageable with this and connections for connection of supply lines between the tractor and the semi-trailer, and defines the preamble of claim 1.
a fifth wheel coupling for coupling a semitrailer tractor with a semi-trailer having connection arrangements for connecting electric and pneumatic lines, comprising a kingpin which can be arranged on the semitrailer and has concentrically arranged first connection arrangements for electric and pneumatic or hydraulic lines, and a coupling plate, which can be arranged on the towing vehicle and has at its underside to the first connection arrangements complementarily formed second connection arrangements, wherein the second connection arrangements are arranged in a substantially cylindrical connection housing, and wherein below the coupling plate and adjacent to the connection housing a lifting mechanism for lifting the connection housing is arranged , characterized in that the lifting mechanism is arranged by means of elastic elements movable on the coupling plate.
the fifth wheel can be as simple and safe in any driving situation against dirt and malfunction, in particular contact interruptions protected.
a fifth wheel is provided for coupling a semitrailer tractor with a semi-trailer with connection arrangements for connecting electrical and pneumatic or hydraulic lines, the semi-trailer having a kingpin concentrically arranged first connection arrangements for electric and pneumatic or hydraulic lines, and wherein the towing vehicle below the Clutch plate to complementarily formed second connection arrangements, wherein the second connection arrangements are arranged in a cylindrical connection housing and wherein below the coupling plate and adjacent to the connection housing, a lifting mechanism for lifting the connection housing is arranged.
connection arrangements It is advantageous that as little space as possible is required for the connection arrangements. This is achieved in that the lifting mechanism is arranged annularly around the connecting housing.
connection housing is ensured regardless of its altitude. This is achieved by that the dirt cover under the coupling plate is slidably disposed by the closing movement of the lock piece or by the retraction movement of the kingpin.
FIG. 1 is a fifth wheel 1 with a lifting mechanism 2 for a connection housing shown in perspective.
FIG. 1 shows the underside of a coupling plate 3.
the lifting mechanism 2 is arranged elastically on the underside of the coupling plate 3. The thus possible movement of the lifting mechanism 2 in the X-direction, ie in the direction of travel and in the direction in which the semi-trailer moves with the kingpin in the retraction region 4 of the coupling plate 3 during the coupling process, is realized by the attachment with an elastic element.
the elastic mounting of the lifting mechanism 2 serves on the one hand to compensate for both the height clearance in the Z-direction and the radial clearance in the XY plane, so that the lifting mechanism 2 can be aligned in each case to the respective kingpin.
This alignment or centering of the lifting mechanism 2 ensures that the two complementary parts of the connecting arrangements are positioned correctly to each other and at the same time can not change their relative position to each other by the elastic bias in all driving maneuvers, whereby a secure electrical and pneumatic or hydraulic connection is ensured ,
a lever arm 17 can be seen, which is connected to a sleeve 7, which has a control contour 8.
FIG. 2 is the fifth wheel 1 of FIG. 1 shown cut.
FIG. 2 is the fifth wheel 1 in the coupled position, that is shown in the operating position while driving.
the kingpin 9, which is connected to the semitrailer, not shown here, has a central bore 10 for electrical and pneumatic lines 12,13.
a first connection housing 11 with a pneumatic or hydraulic line 12 and an electrical line 13 can be seen.
the lifting mechanism 2 is shown with a second connection housing 14.
the connecting housing 14 is essentially a cylindrical housing with coaxially arranged connectors for electrical and / or pneumatic lines, which are designed and arranged to match the pneumatic or hydraulic lines 12 and the electrical lines 13 in the king pin 9.
the housing 14 is moved by a control contour 8 in the sleeve 7 along the Z-axis.
a dirt cover 15 can be seen adjacent to a collar 16 at the lower end of the kingpin 9, a dirt cover 15 can be seen. In the Operating position, when the king pin 9 is engaged in the coupling plate 3, the dirt cover 15 is pushed laterally away.
FIG. 3 shows the lifting mechanism 2 in the rest position, with the connecting housing 14 in the lower retracted position and the dirt cover 15 in the closed position.
FIG. 4 the same lifting mechanism 2 is shown in the operating position.
the dirt cover 15 is shown pushed laterally away and how the upper portion 18 of the connecting housing 14 is extended in the Z direction upwards.
the dirt cover 15 is connected at a pivot point 20 radially movable with the lifting mechanism 2.
the displacement of the dirt cover 15 to release the opening to the connection arrangements in the connection housing 14 is determined by the in FIG. 1 shown lock piece 22, which releases the space for the king pin 9 below the coupling plate, or triggered by the collar 16 of the retracting kingpin 9.
the dirt cover 15 is pushed by a spring over the connecting housing 14 again.
Another possible favorable embodiment is a mechanical holding device 21, which allows a mechanical support of the lifting mechanism 2 on the top of the collar 16 of the kingpin 9.
the holding device 21 can be provided for the sole or additional fixing or centering of the lifting mechanism 2 with respect to the kingpin 9.
the sleeve 7 with the lever arm 17 is in the Figures 3 and 4 each represented in one of the end positions.
the first end position of the lever arm 17 with the sleeve 7 and the control contour 8 in FIG. 3 causes the coaxial connection assemblies in the connector housing 14 in the Z-axis direction be pulled down.
FIG. 4 the second end position of the lever arm 17 and the sleeve 7 is shown with the control contour 8.
the lever arm 17 is actuated by an actuator, not shown here, which is arranged between the end of the lever arm 17 and the mounting plate 19.
the coupling process consists successively of the following steps: retracting the kingpin 9 in the retraction area 4, moving the lock piece 22 and the dirt cover 15, locking the lock piece 22 and the lifting mechanism 2 and raising the connection housing 14 for coupling the electrical and pneumatic or hydraulic lines 12, 13 in the kingpin 9.
